Eagle Instruction Manual Calibration • 42
Calibrating the Eagle
Press and hold the SHIFT/▼ button, then press the DISP/ADJ button.
The Calibration menu displays.
NOTE: The following screens illustrate a four-gas Eagle with the data
logging option and are intended as examples only. Your Eagle
may display slightly different screens.
The Eagle’s Calibration menu includes two methods of calibration:
Auto Calibration and Single Calibration.
• Auto Calibration: This method allows you to calibrate all four
sensors simultaneously. It is designed for use with the RKI Four-
Gas Calibration Cylinder and is the quickest and easiest method to
calibrate the Eagle.
• Single Calibration: This method allows you to calibrate one sensor
at a time. Use this method if you are only calibrating one or two
sensors, if you are calibrating non-standard toxic sensors, or if you
are not using the RKI Four-Gas Calibration Cylinder.
Calibrating with the Auto Calibration method
This section describes calibration using the Auto Calibration method.
To calibrate using the Single Calibration method, see “Calibrating
with the Single Calibration method” on page 44.
1. Use the AIR/▲ and SHIFT/▼ button to place the prompt next to
the AUTO CALIBRATION menu option.
2. Press the POWER/ENTER button to display the Calibration
Values screen.
The gas concentrations displayed in the Calibration Values screen
must match the gas concentrations listed on the Four-Gas Calibration
Cylinder. If all concentrations match, go to step 7. If one or more
concentrations do not match, continue with step 3.
